I went home on 27th February and didn't realize that the increment of Seoul subway fare has increased since 25th of February cause I just stayed home on the weekend and M.Y. family sent me to the airport.

Right after I reached Incheon Airport, I used the local bus to go to Incheon when I returned to Korea on 5th March and still didn't realize it until after I used the subway. I saw the charge was 1,050won. What happened?

So I thought that there's something wrong with my T-Money card but when M.Y. told me that the petrol price was so high recently, it hit my thinking cap then. Yikes!!

Bad..this is bad.

If you use T-Money card, your basic fare will start with 900 won plus the increased fare of 150 won.
So I guess that they opted for 150 won increment instead of 200 won but still... T_T
